STEAM AND WATER HEAT RADIATING APPARAT'US.

SPECIFICATION forming part of Letters Patent No. 279,721, dated June 19, 1883.

Application filed December 29.1882. (No model.)

T wZLwhom it may concern:

Be it known that I, LUDWIG GnUsIus, of Kaiserslautern, Bavaria, Germany, have invented a new and Improved Steam and WVater Heat Radiating Apparatus, of which the following is a full, clear, and exact description.

Heretofore hot-water or steam heating have been used quite extensively. The defect of the former is mainly that it requires a considerable time to raise the temperature of the wa ter sufficiently to enable it to heat the room, which heat is, however, retained for a long time in the water, and thus prevents the rapid falling of the temperature in the room. 011 the other hand by means of steam a room can be heated very rapidly; but as soon as the steam is turned off the temperature falls and the room is cooled very rapidly, and thus requires the heat to-be turned on after a short time, thus making it almost impossible to give,

the room a uniform temperature.

The object of my invention is to provide a new and improved steam and water heat radiating apparatus, which combines the advantages of both steam and water heating,.and

-which at the same time is devoid of theabovedescribed defects.

The invention consists in a radiator or tube constructed with a partition which divides the radiator into two compartments, of which one is for steam and the other for water, which compartments have a common inletcock and separate outlet-cocks,whereby if all the cooks are open'the apparatus'will operate as an ordinary steam-radiator; but if the cock of the water-compartment is closed the water of condensation accumulates in the said compartment, and is heated by the steam in the adjoining compartment. compartment heats the room very rapidly, and the heated water in the other compartment retains the heat and prevents the rapid falling off of the temperature.

Reference is'to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

my improved steam and water heat radiating apparatus. Fig. 2 is a cross-sectional elevation of the same on the line at as, Fig. 1. Fig.

Fig. 9 is a modification showing a longitudinal sectional elevation of a pipe-shaped radiator of my improved construction. Fig. 10 is a cross-sectional elevation of the same. Figs. 11, 12, 13, and 14 are crosssectional elevations of modifications of the same. Fig. 15 is a 1011- gitudinal sectional G1GXZLl lOD of the double cock used with my improved radiator. Fig. 16 is a cross-sectional elevation of the same on the line 1 y, Fig. 15.

A cast-iron radiator-box, A, is provided with a partition, B, which divides the box A into two compartments, A. and A, and the said partition B is preferably so constructed that it has a very large radiating or heating suriace-that is to say, it is bulged out, corrugated, curved, or provided with ribs, as may be desired. A greater or less number of the above-described boxes or radiators A are combined, according to the size of the room that is to be heated or the desired size of the heater. To simplify matters I will describe the apparatus shown in Fig. 1, which consists of two sections A. Each section A is provided at its top and bottom with a neck, I), as shown, and the edges of the partitions B extend to the edges of the necks, except in the case of the uppermost section A, in which the upper edge neck I) of the uppermost section A a steaminlet pipe, 0, is secured,which is provided with a valve, D, and to the bottom neck I) of the 1 lowest section a double elbow, E, is attachedthat is, an elbow with two passages and to the lower end of the elbow E a double cock, F, is attached, which is provided with two valves, F and F one for each passage or channel of the elbow E, the two passages in the cock F- terminating in a neck, G, to which the pipe leading to the condensation-water receiver is secured. If desired, the double-cock F may be screwed directly to the neck I) of the bottom section A; but the construction shown and described above is preferred; or two separate cocks may be used instead of a double cock. If the valves D, F, and F are opened, the radiator will operate the same as any ordinary steam-heater radiatorthat is, the steam 1O enters through the pipe 0, passes through the 2 A and down through the same and through the double cock F to the condensation -water receiver. The water in the said compart ments A being in contact with the surface of the partition B, which partition is heated by the live steam in the compartments A the said water will be heated by the steam that is turned on to enter the compartments A". The steam in the compartments A will thus heat a room very rapidly, and if the steam 0 is turned off, the radiator will not cool immediately, as the hot water in the compartment A retains the heat for a long time, which heat is radiated by the walls of the sections A; and thus by means of my improved radiator I com- 5 bine the advantages of steam heating with those ofhot-water heating, and can easily regulate the temperature of a room as may be desired.

I have described only the devices shown in Figs. 1, 2, and 3; but the device may be modified in different ways without changing the operation, the main features of the invention being retained in all, which are as follows: a partition dividing the radiator into 'a steam 4 5 and water compartment, which compartments communicate with each other at the single inlet-cock opening into both compartments, and each compartment having a separate outletcock, the inlet and outlet cocks not .being shown in the drawings of the modifications.

For instance, in the modification shown in Fig. 4 the two inner compartments, A for receiving the steam, are surrounded by the water, the

sections being formed somewhat differently. from those shown in Fig. 1.

I11 the modification shown in Fig. 5 a steam-compartment, A is formed between two watercompartments, A. In the modification shown in Fig. 6 a series of sections are united, each containing a water compartment and a steam-compartment, the severalwater-compartments and the several steam-compartmentsbeing connected by means of crosspipes, whereby a very large radiatingsurface is obtained. In the modifications shown in Figs. 7 and8 aseries of rings constructed like those shown are placed above each other and united, and in this case an annular water-conr partment, A, containing two steam-compartments, A at opposite sides of the ring, "is formed. In the modification shown in Figs. 9 to 14, inclusive, the radiator is formed of a series of pipes each provided with a partition, dividing the'pipes' into a water-compartment, A, and a steam-compartment, A The pipes may be cylindrical in cross-section, oblong, square, or of any other suitable shape, and the transverse partition may be straight or curved, as may be required. The end sections are provided with necks b b, as shown; but the middle sections are simply provided with a transverse partition, so that any number ofintermediate sections may be united between the end sections, provided with the necks Z), to form a heating-tube of the desired length. If desired, the tube radiator-box may be provided with ribs H, as shown in Figs. 2, 3, and 9 to 14, for the purpose of increasing the ra diating-surface. It will be seen that in all cases I provide a radiator box, tube, or other vessel or receptacle which is provided with a partition which divides it into two compartments-one for steam and one for water which compartments are so connected at the steam-inlet pipe that the steam can pass into both compartments and the condensatiouwater flow from one compartment into the other after one compartment has been filled, and that each compartment has a separate outletcock.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is.-

1. A radiator provided with a partition dividing it into a steam and a water con'ipartment, which compartments communicate with each other, as set forth, and having one inletcock opening into both compartments, and each compartment having a separate outlet-cock, substantially as described, and for the purpose set forth.

2. The combination, with the radiator A, provided with the partition B, dividing the radiator intothe hot-water compartment A and the steam-compartment A of the inlet cock D, leading into both compartments, the elbow E, and the double cock F, substantially as described, and for the purpose set forth.

I LUDWIG GRUSIUS.
